"I am, indeed, so disgusted with learned quackery that I take some interest in honest, humane, and strongminded empiricism; for it has done more for our art, in all ages and all countries, than all the universities since the time of Charlemagne." Professor Benj. Rush, of the greatest and oldest Allopathic College in America, says: "Remember how many of our most useful remedies have been discovered by quacks. Do not therefore be afraid of conversing with them, and of profiting by their ignorance and temerity. Medicine has its pharisees as well as religion. But the spirit of this sect is as unfriendly to the advancement of medicine as it is to Christian charity. In the pursuit of medical knowledge let me advise you to converse with nurses and old women. They will often suggest facts in the history and cure of disease which have escaped the most sagacious observers of nature. By so doing, we may discover laws of the animal economy which have no place in our system of Nosology, or in our theories of physic. The practice of physic hath been more improved by the casual experiments of illiterate nations, and the rash ones of vagabond quacks, than by all the once celebrated professors of it, and the theoretic teachers in the several schools of Europe, very few of whom have furnished us with one new medicine, or have taught us better to use our old ones, or have in any one instance at all, improved the art of curing disease." Dr. Adam Smith says: "After denouncing Paracelsus as a quack, the regular medical profession stole his `quack-silver' mercury; after calling Jenner an imposter it adopted his discovery of vaccination; after dubbing Harvey a humbug it was forced to swallow his theory of the circulation of the blood." Professor J. Rodes Buchanan, Boston, says: "Mozart, Hoffman, Ole Bull, and Blind Tom were born with a mastery of music, as Zerah Colburn with a mastery of mathematics, as others are born with a mastery of the mystery of life and disease, like Greatrakes, Newton, Hutton, Sweet and Stephens, born doctors, and score of similar renown." Professor Charles W. Emerson, M.D., the well known resident of the Monroe Conservatory of Oratory, of Boston, says: "The progress in therapeutics has and still continues to come from the unlearned. Common people give us our improvements and the school men spend their time in giving Greek and Latin names to these improvements, and building metaphysical theories around them."
